2 Claims. (Cl. 299-45) My invention relates to a lawn spraying device.

An object of my invention is to provide a device for spraying liquidinsecticides or other solutions, and wherein the sprays are concentratedwithin a chamber so that the wind or air currents will not convey thespray to plants where it is not desired.

A further object of my invention is to provide a spraying arrangementwherein the device will function regardless of the contour of theground, and wherein a collapsible arrangement will permit such use.

A further object of my invention is to provide a convenient carriagearrangement for supporting the spraying devices, and which can bealternately converted for other purposes.

With these and other objects in view, my invention consists in theconstruction, arrangement, and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure l is a side elevation of the arrangement with portions beingtaken in cross section,

Figure 2 is a plan view of Figure 1, and

Figure 3 is a detail.

I have used the character to designate an arcuate hood having a fairlysubstantial width laterally, and which includes the downwardly extendingside walls 11, and end walls 12.

Attached by means of suitable stove bolts 13 about the lower edge ofthis chamber is a fabric member having side walls 14 and end walls 15,this fabric member being adapted to fairly closely engage the groundsurface.

Passing through the center of the hood portion 10 at 16 is a shortnipple 17 which communicates with the transverse pipe 18, which pipecommunicates with a series of equally spaced spray heads 19.

The hood portion 10 is supported to the arcuate strap members 20 bymeans of the bolts 21, the strap members 20 terminating in the forwardlyinwardly converging portions 22 to which is attached the cross member23, in which cross member is pivotally mounted the vertical shaft 24 ofa fork member 25 to which is journalled at 26 a forward wheel 27.

Further braces 28 are provided to strengthen the arrangement.

The members 20 also extend into the pair of horizontally positionedportions 29 which are bolted at 30 to the horizontally positioned strapmembers 31 between which members is attached a base member 32 upon whichis secured the gas engine 33, the gas engine 33 driving the pulley 34over which passes the belt 35 which passes over a further pulley 36 fordriving the pump 37. Attached at the ends of the members 31 at 33 arethe upwardly inclined handle members 39 terminating in the graspingportions 40.

Secured to the members 31 are the brackets 41 in 2,740,664 Patented Apr.3, 1956 which is secured the transverse shaft 42 upon which arejournalled the side wheels 43.

Secured at 44 to the further bracing members 45 are the straps 46 whichenclose and retain the tank 47, the tank 47 being for the purpose ofcontaining the insecticide or other liquid which is to be sprayed, andcommunicating with the tank 47 at 48 is the tube 49 which communicatesto the pump 37, and also communicating from the pump 37 is the shortpipe 50 to which is attached the flexible tube 51, the tube 51 beingattached to the nipples 17. The bracing members 45 are secured by meansof the bolts 52 to the strap members 20. The character 53 designatesfurther bracing members.

It will now be seen that as the device is pushed forwardly by graspingthe handle portions 40, that the en gine will drive the pump 37, andwhereby the liquid in the tank 47 will be sprayed through the sprayheads 19, such spray heads forcing the liquid downwardly upon the plantsand the like, and it will be noted further that the sprays will beconcentrated within the enclosed chamber as explained, whereby suchsprays can not pass outwardly beyond the confines of the chamber.

The flexible fabric member comprising the walls 14 and 15 also insuresthat the spray is concentrated and at the same time allows the device topass over plants and irregularities due to the flexible nature of thefabric.

Also, by removing the bolts 30 and 52, the concentrating chamber 10 etc.can be removed from the unit, the right-hand portion of the device asseen in Figure 1 can then be wheeled to any point desired independentlyof the balance of the arrangement, and with a lengthened tube beingattached to the pipe 50 whereby the unit can then be used for handspraying and the like.

The device is thus readily adaptable for either condition, and it willthus be seen that the device fulfills a variety of needs and willconcentrate the spray directly to the surface required, without dangerto other plants and the like.

Some changes may be made in the construction and arrangement of theparts of my invention without departing from the real spirit and purposeof my invention, and it is my intention to cover by my claims anymodified forms of structure or use of mechanical equivalents which maybe reasonably included within their scope.

I claim as my invention:

1. A lawn spraying device comprising a hollow casing having end, top,and side walls, a spraying unit mounted in said casing including alaterally positioned pipe including a plurality of spray outletsattached thereto, means for forcing spraying liquid into said pipe,including a carriage portion attached to said hollow casing, a tankmounted on said carriage portion, said tank including said liquid, apump communicating with said tank and said pipe, means for driving saidpump, means for providing detachment of said carriage portion from saidcasing whereby said pump can be employed for operation independently ofthe casing, means for supporting said casing including a pair ofsubstantially arcuate strap members attached to the casing, and having aforward wheeled portion.

2. A lawn spraying device comprising a hollow casing having end, top,and side walls. a spraying unit mounted in said casing including alaterally positioned pipe including a plurality of spray outletsattached thereto, means for forcing spraying liquid into said pipe,including a carriage portion attached to said hollow casing, a tankmounted on said carriage portion, said tank including said liquid, apump communicating with said tank and said pipe, means for driving saidpump, means for providing detachment of said carriage portion from saidcasing whereby said pump can be employed for operation independently ofthe casing, means for supporting said casing including a pair ofsubstantially arcuate strap members attached to the casing, and having aforward wheeled portion, wheels journalled on said carriage portion.
